ETFE Film Tent Membrane Durability and Ecology | Tomas Engineering Thailand Samut Prakan

ETFE film (ethylene tetrafluoroethylene) is a type of plastic film manufactured from a polymer material called ethylene tetrafluoroethylene. This material possesses special characteristics such as durability, lightweight properties, and resistance to harsh environments. ETFE film is frequently used for roofs and walls in architectural structures where transparent and lightweight materials are particularly required, such as in stadiums, exhibition spaces, and energy-efficient buildings.
Evolving architectural possibilities—lightweight, highly transparent, and waterproof design roofs realized with ETFE film. It leads architectural expression for a new era.
ETFE film is a new material that revolutionizes next-generation architectural design due to its excellent physical properties. It has been adopted in major global architectural projects such as the Eden Project in the UK and the Allianz Arena for the German World Cup, demonstrating its potential as a substitute material for glass. With its ultra-lightweight nature and high transparency, it reduces the load on the building structure and allows more natural light to enter, thereby achieving both reduced environmental impact and improved habitability.
Features
Ultra-lightweight: Weighing only 440g/m², it contributes to reducing the load on the building structure and improving seismic resistance.
High Transparency: With a very high visible light transmittance of 90.8%, it allows ample natural light into the interior.
High Durability and Anti-fouling Properties: Excellent weather resistance and chemical resistance, with minimal yellowing/clouding due to aging, maintaining transparency for a long period.
Thermal Insulation Performance: By forming the film into a cushion shape and creating an air layer, it achieves a thermal transmittance equivalent to glass.
Lighting Effect: It pairs well with LED lighting, enhancing nighttime visual effects.
